Upbeat England boss Sven-Goran Eriksson vowed to follow his win in Liechtenstein by overcoming Turkey on Wearside this week.

Upbeat England boss Sven-Goran Eriksson vowed to follow his win in Liechtenstein by overcoming Turkey on Wearside this week.

The Swede's team failed to impress in yesterday's 2-0 Euro 2004 qualifying victory over the outsiders.

But Eriksson remained defiant in the face of frustration at his team's largely unconvincing display, maintaining that they have not gone backwards since the World Cup.

The 2-0 victory in Vaduz did at least ensure that England registered their second win in five games since last summer's tournament.

However, with Liechtenstein hitting the post and having a shot cleared off the line late on, it was clear that England will have to imporve significantl yo beat Turkey at Sunderland's Stadium of Light on Wednesday.

Once again, the England coach was indebted to his two world-class finishers - Michael Owen and David Beckham.

Owen struck his 20th goal for his country midway through the first half, while Beckham converted a 20-yard free-kick just after the interval.

Eriksson, wha has an injury doubt over Emile Heskey ahead of the Turkey game, declared: "I am sure that we haven't gone backwards since the World Cup.

"It was a really bad result to draw at home to Macedonia but I'm not worried about the future for England.

"I am convinced that we will do a very good game next week. I cannot tell you the result but we will play good football and give Turkey a battle, I'm sure of that."

Liechtenstein, who have only secured one competitive victory in their history, gave England some early scares before coming even closer to pulling a goal back late on.

Eriksson nevertheless insisted: "We did what we should have - a good professional job.

"Maybe we didn't start as well as we should have done and, for sure, we didn't finish as well as we should have done.

"At the end, we lost a bit of concentration and that's not good. But I was pleased with most of the game.

"We scored twice and could have scored more.

"We got three points and I'm happy with that.

"Liechtenstein are improving year by year. They have some good players and they were well organised."

Eriksson is hoping that Sol Campbell will be fit to face Turkey, but he now faces another injury worry over Heskey that could potentially open the door to Wayne Rooney, a 79th-minute substitute in Vaduz.

"Steven Gerrard and David Beckham were both excellent.

"I took them off for two reasons - as we are playing again on Wednesday and because they would have been suspended for that game if they had got booked," he explained.

"My plan was also to take off Paul Scholes, who was in the same situation, but unfortunately Emile Heskey got a knock on his knee which became worse and worse. That's why I took him off instead."

Liechtenstein coach Ralf Loose reflected on his side's lack of good fortune in failing to score at least once.

"I am satisfied with my team and it was bad luck that we didn't score," he said.

"I would congratulate England on a fine performance and wish them luck on Wednesday night against Turkey, who will be a slightly more difficult test for them."
